I didn't want to dwell on it in the article (and didn't have space anyway),
but pyqt turned out to be a bit of a pain.
There's no official documentation -- or at least nothing
that's obviously official -- and a lot of
the examples on google are out of date because of API changes.
None of the tutorial examples explain much, and they never demonstrate
the practical features I'd want to do in a real app.
It was surprisingly hard to come up with an application idea
that worked well, looked good and was still easy to explain.

And don't get me started on this whole "Slots and signals are
revolutionarily different even though they look just like the callbacks
every other toolkit has used for the last three decades" meme.
I'm sure there is a subtle technical difference -- but if there's
a difference that matters to the average UI programmer, their
documentation sure doesn't make it clear.

All that aside, PyQt (and Qt in general) does produce very pretty apps
and is worth trying for that reason.

The suit images in the article are adapted from some suits I found on
Wikimedia Commons
(the "Naipe" set).
I wanted them to look more 3-dimensional, so I applied my
blobipy GIMP
script as well as scaling and resizing them.
I really liked those shiny-looking Tango heart and spade emblems (also
on the Wikimedia Commons page) but I couldn't find a diamond or club
to match.

The poker program I wrote has menus and a second round of dealing,
where you can mark off the cards you want to keep.
I couldn't fit all that in a 700-word article, but
the complete program is available here:
qpoker.py
or you can get it in a tarball along with the suit images at
qpoker.tar.gz.
